First of all, with these dimensions it is NOT a cube , but a 'CUBOID'.

T.S. = 2( lw + wh + lh)

T.S. 2((8 x 3 ) + (3 x 5 ) + (8 x 5 ))

T.S. = 2(24 + 15 + 40)

T.S. = 2(79)

T.S. = 158 units^(2).

How do you find the height of a box given the width depth and surface area?

divide surface area by width Sorry It is a little more complicated than that. Surface area = (2 X length X width) + (2 X length X height) + (2 X width X height) Solve for height Surface area - (2 X length X width) = 2height(length + width) (Surface area - (2 X length X width))/2(length + width) = height

How do you find length and width with just the height and surface area?

To get the surface area, someone had to multiply length times width. So what we would need to do is take our surface area, divide by our height, which is our width, and get our length. So if SA stood for surface area, and h stood for height, we'd take SA/h to get the length.
